The sun hung low over the Pacific, casting a golden haze across the shoreline as waves crashed rhythmically onto the sand. The breeze was salty, warm, and carried just enough sting to remind everyone that they were working, not vacationing. The team had claimed a wide stretch of beach as their makeshift training ground for the afternoon—cone-marked sprint lanes, improvised obstacles, and a large cooler half-buried in the sand.
Callen, Sam, Kensi, and Deeks were well into their second hour of laps, sprints, and bodyweight drills—shirts clinging, lungs burning, and patience thinning. Somewhere in the middle of warmups, Deeks—sweaty, overconfident, and clearly not thinking it through—had asked Nell to keep time.
She had taken the role seriously. Very seriously.
"Let's move, people! If you've got energy to complain, you've got energy to hustle!" Nell's voice rang out, firm and clear, cutting through the sound of crashing surf like a whistle. She stood with her feet planted beside the timer cone, stopwatch in one hand, sunglasses perched high on her nose, and her ponytail bouncing with every sharp pivot she made. The look on her face could've made a Marine straighten up.
Deeks had immediately regretted his choice. Kensi, on the other hand, had been grinning for half the session.
Callen jogged his way up the sand incline toward her, legs burning, shirt clinging to his back, breath coming in hard but steady. Sweat dripped down his temple, and sand itched at the seams of his sneakers, but his attention wasn't on the discomfort. It was on her.
She stood like she belonged there—confident, grounded, a little terrifying. There was a fire in Nell Jones that people didn't always see coming, but Callen? He'd seen it for years. That mind of hers, sharp enough to cut glass, paired with an edge he was learning not to underestimate. Not anymore.
She didn't look up as he approached. "Fifteen seconds slower than your last lap," she said, tapping the stopwatch.
He grabbed a water bottle from the cooler and took a long drink, studying her over the rim. "That stopwatch broken?"
"Nope," she said with irritating cheerfulness. "It's just brutally honest. Like me."
He smirked, wiping his face with his wrist. "You're enjoying this way too much."
She finally looked up, and there it was—that glint behind the sunglasses, the curve of a smirk she was trying not to give away. She was having a blast bossing them around, and Callen had to admit—watching her like this, in her element and completely unapologetic about it—it was magnetic.
"Maybe. You gave Deeks the power to delegate, remember? I just accepted my mission."
"And decided to go full drill sergeant?"
"Structure boosts performance."
"You mean it boosts your ability to boss us around."
"Semantics," she said smoothly, stepping a little closer, tilting her head. "Don't tell me you're not loving the challenge."
He let his eyes linger on her for a beat longer than usual. She wasn't bluffing—she never did—but there was something behind her confidence now that pulled at him. She was bolder lately, more sure of herself in every way, and he was noticing. More than he meant to.
"You've got a talent for this," he said. "Should I be worried?"
"Only if you're thinking of slacking off again," she shot back, her tone playful but edged with something else—something he couldn't quite name, but wanted to.
He leaned in, just slightly, testing the waters. "Define slacking."
She didn't back down. Didn't even blink. "Stopping to flirt with the timekeeper probably qualifies."
His grin spread slowly—uncharted, real. The kind that didn't get much use in the field but came out for moments like this. For her.
"Then I guess I'm in trouble."
Nell didn't roll her eyes, not really. She just smirked and held up the stopwatch. "Time's ticking, Agent Callen."
He gave her a mock salute and jogged off, but glanced back once, catching the faint smile she didn't quite hide.
He wasn't sure when this had shifted. When her sharp, clever comments stopped being just clever and started getting under his skin in a different way. Maybe it was seeing her in the field more, maybe it was how she always called him on his crap, or maybe it was that she saw straight through him—and didn't flinch. That part stuck with him.
Sam powered past Nell moments later, breathing steady as ever.
"Soft spot's showing, Jones," he muttered.
She didn't deny it. Didn't have to. Her gaze was still half-focused on where Callen was disappearing down the beach.
Back down the track, Kensi was dragging Deeks by the sleeve.
"Come on," she groaned. "She's gonna make us do burpees if we don't finish."
"She's terrifying," Deeks gasped. "Like, adorable, but terrifying."
Callen, having looped back around, caught the end of that and barked out a short laugh. "That about sums it up."
By the time the session wound down, the sun had begun its slow descent toward the horizon, painting the beach in soft amber tones. The team sprawled on towels and driftwood, muscles aching, moods lighter. Nell finally clicked off the stopwatch and walked over, dropping it onto the cooler with a dramatic little flourish.
Callen passed her a water bottle, and as she took it, their fingers brushed. Just long enough to notice. He didn't move away right away.
"You gonna let us rest now?" he asked, voice low and casual.
She took a sip and gave him a sideways look. "Maybe. You did pick up the pace on that last lap."
"That because you motivated me," he said, still watching her. "Drill sergeant and muse. Impressive combo."
She snorted softly, but her cheeks had flushed ever so slightly. "Flattery won't get you out of cooldown stretches."
He leaned back on his elbows in the sand, eyes still on her, unreadable but present. "Worth a shot."
She didn't say anything back right away. Just smiled quietly to herself, taking in the view—the waves, the sky, the way Callen's gaze lingered a little longer than it used to.
Nearby, Sam watched the exchange with quiet amusement. Kensi nudged Deeks, who whispered, "Told you. She broke him."
And maybe she had.
But as Callen looked up at her—really looked—he was starting to think he might've walked into this one willingly.
